An object of 50 kg gets the speed of 10 m/s in 5 second from zero velocity. Calculate the required force applied by engine of the car? (in N)
Initial velocity (u) = 0, final velocity (v) = 10m/s, time (t) = 5 second, Mass (m) = 50 kg,
Therefore, force (F)=?
We know that, Force (F) = m v−ut
Therefore, F = 50 kg 10−0 m/s5s
= 50 kg x 2ms-2
F = 100kg ms-2 = 100N
Thus required force = 100 N
